This surface skimmer is intended for aquarists who want to remove surface film from the water without drawing debris into the filter. It mounts on the filter outlet, which is the key difference from intake-side skimmers. It is dedicated to the Aquario NEO FLOW L outlet and listed as compatible with several popular external filter brands.
Why it matters
- Mounted on the outlet, it pulls in surface debris and returns it straight to the water, so food, leaves, shrimp and fry are not trapped in the filter where they could decompose.
- A three-armed star insert placed inside the skimmer stops debris from passing through it.
- An angled internal tube lets you adjust the air supply: turning it fully closes the air intake, which switches aeration off completely.
- Because air is not drawn in through the intake side, the filter is not prone to air locking.
